There, actually, is a background story to this one.
This cute little amateur Sumi comes from the city of Messtetten (Germany).
The reason why she filmed herself, well, apart from being a horny camslut, is that the clips were only ment to be seen by her boyfriend who, at the time being, was a soldier serving his country outside of Germany (some say that he was stationed in Afganistan), so, basically, the clips were ment to be little presents for him so he would feel less homesick.
